Patent CA-1330590-C (CA)
Title: Multiplex signal processing apparatus
Inventor: KAGEYAMA SADASHI
IPC: H04N5/44
Filed: 1987-07-13
Granted: 1994-07-05
Abstract: ABSTRACT OF THE DISCLOSURE A multiplex signal processing apparatus in a signal transmitting and receiving system includes at the transmit-ting side:  a first amplitude-modulator for modulating a first carrier by a main signal to obtain a vestigial side-band, amplitude-modulated main signal; a second amplitude-modulator for modulating a second carrier which has the same frequency but differs in phase by 90° from the first carrier by a multiplex signal to obtain a double sideband, amplitude-modulated multiplex signal; an inverse Nyquist filter for filtering this signal to obtain a vestigial sideband, amplitude-modulated multiplex signal; and an adder for adding the vestigial sideband, amplitude-modulated main and multiplex signals to obtain a multiplexed signal.  The apparatus at the receiving side includes:  a Nyquist filter for filtering the multiplexed signal; a carrier regenerator for regenerating the first and second carriers from the multiplexed signal; a main signal detector for detecting the main signal from the multiplexed signal passed through the Nyquist filter by using the first carrier; a filter for removing quadrature distortion from the multiplexed signal; and a multiplex signal detector for detecting the multiplex signal from the multiplexed signal passed through the filter by using the second carrier.  By inverse Nyquist filtering the auxiliary signal in quadrature to the picture carrier, a normal synchronous receiver will produce a conventional television signal without distortion (crosstalk) caused by quadrature distortion of an auxiliary signal containing additional picture information while at the same time allowing relatively simple demodulation of the auxiliary signal in improved receivers without adding distortion.

Title: Bimetal actuated lock
Inventor: CASE RICHARD P
IPC: D06F37/42
Filed: 1987-08-11
Granted: 1990-12-27
Abstract: BIMETAL ACTUATED LOCK     ABSTRACT OF THE DISCLOSURE          A door locking device for an appliance such as a washing machine has a rotatable lock lever actuated to engage a latch carried by the door to hold the door in a closed position.  The lock lever is actuated by a bime-tallic element which is adapted to be connected in series with the drive motor when the washing machine is in the spin condition so that the electric current passing through the drive motor passes through the bimetallic element and the resulting heating and deflection of the bimetallic element actuates the lock lever.  The unit also carries an interlock switch actuated by the latch mechanism to prevent operation when the door is open.  A shunt switch is provided to close  electrical contacts when the bimetallic element and lock lever are deflected to the locked position to shunt current past the bime-tallic member to prevent further heating and to insure a substantially constant unlock time.

Title: Circuit for removing unwanted slope transitions from an incoming signal
Inventor: JANZ DONALD WALTER
IPC: H03K5/26
Filed: 1988-02-26
Granted: 1995-08-15
Abstract: Provided is a circuit for removing an unwanted temporal por-tion of an incoming signal and for differentiating that signal with respect to a reference voltage level.  It includes an input for receiving the incoming signal current through an input cap-acitor, a differential amplifier for converting input charging current into a voltage with respect to a reference voltage, and a charging capacitor for holding a voltage level representative of the charging current supplied to the differential amplifier during times when the unwanted input signal portion is to be re-moved from the circuit's output.  A current sink and source pro-vides a reset period voltage charge to the input capacitor during times when the unwanted portion is to be removed from the out-going signal.  A switch responds to a reset signal immediately preceding or on the occurrence of the unwanted signal portion.          The charging capacitor means is charged during the gradually sloping portion of the incoming signal so as to hold a voltage level representative of the incoming charging current when the rapid slope transition (unwanted signal portion) occurs.  During such time the reset signal causes the switch to allow the charg-ing capacitor to provide its stored voltage level via the current sink and source to the differential amplifier and input capacitor.

Title: Continuous round baler with accumulating trailer
Inventor: RATZLAFF HOWARD J
IPC: A01D90/08
Filed: 1988-04-22
Granted: 1992-11-03
Abstract: CONTINUOUS ROUND BALER WITH ACCUMULATING TRAILER            Abstract of the Disclosure The  baler  has  a  "vertical"  bale  starting chamber in which the upwardly moving rear belts and the  downwardly moving  front  belts  cooperate  to tumble and roll incoming material into a bale.  When the bale reaches full size in the expanded chamber, the bale is lifted while still in its chamber to a wrapping station where it continues to spin as a binding wrapper is applied.  During the lifting of the finished bale and subsequent application of the wrapper, fresh material entering the continuously moving baler is confined beneath the finished bale in a new starting chamber, whereupon the cycle is repeated.  As the new bale grows, a discharge ramp becomes formed by certain stretches of the belts and rollers to gravitationally discharge the wrapped bale from the baler without stopping advancement of the machine.  An accumulating trailer is hitched to the baler in a position to receive bales from the discharge ramp as they gravitate down the same and to temporarily store the accumulated group of bales until the operator selects a site for dumping the bales.

Abstract: Cryptographic equipment, in which the crypto variable (code) that is to be kept secret is stored in the device, require a security classification that corresponds to the classification of the code to be kept secret.  However, use of the cryptographic device is made extremely difficult by this since it must as a rule be kept locked, for example in a safe.  In order to give such a cryptographic device a lower security classification than the crypto variable (code) used with it, it is proposed to make the authorization of use of the cryptographic device dependent on user identity cards (UAKn) assigned to various authorized users, the cards being nonvolatile memories that can be overwritten and in which a user-specific external CIK (crypto ignition key) (Xn) is stored which, by linking it to an internal CIK (In) stored for each authorized user internally in a user partial memory (URn) of a variable memory (VSP), results in the crypto variable code (C) with which the crypto variable (V) required for adjusting and controlling the code sequence generator (SFE), the crypto variable being merely stored in a crypto variable partial memory (KVS) in enciphered form, can be deciphered.
